Controlling Collective Quasiparticle Dynamics Beyond Decoherence in Topological Interfaces
Gold nanoparticles placed above a deformed honeycomb plasmonic crystal couple to a chiral topological interface mode. The pseudospin‐split bands ψ+/ ψ− encode spin‐momentum locking, so emitters radiate directionally along the domain wall and share a common phase.

Wavelength and Full‐Polarization Encrypted Orbital Angular Momentum Meta‐Holography
By multiplexing three independent degrees of freedom of light, a single‐layer geometric‐phase metasurface encrypts 24 distinct holographic images across 3 wavelengths, 12 pairs of orthogonal polarizations, and 4 OAM channels, taking advantage of axial chromatic dispersion to reconstruct the color images at the same plane. ABSTRACT Multiplexing multiple

Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs
The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Comb‐Driven Coherent Optical Transmitter for Scalable DWDM Interconnects
A comb‐driven coherent optical transmitter on a Si/SiN platform enables scalable DWDM interconnects by integrating ultra‐compact microring‐assisted modulators and interleavers. High‐baud coherent signaling achieves 400 Gb/s per wavelength and >$>$1 Tb/s multi‐channel transmission, with projected >$>$10 Tb/s per fiber, offering a path toward energy ...

A phase‐change magneto‐optical metagrating combines GST switching with InAs guided‐mode resonances to achieve strong nonreciprocal absorption contrast near normal incidence. A static magnetic bias creates direction‐dependent resonant splitting, while GST crystallization quenches and latches the response.

Interleaved Diffractive Networks for Information Transfer Through Random Diffusers
This work presents a cascaded diffractive optical network that enables information transfer through random, unknown diffusers using passive, interleaved structured layers that mitigate scattering without digital computation. A hybrid optical‐digital version further improves robustness and reconstruction fidelity under distortions, with both simulations
